| Title | Wavlink WL-NU516U1 V240425 Cross Site Scripting |
|---|
| Description | A vulnerability has been found in Wavlink WL-NU516U1 V240425. Affected by this vulnerability is the function sub_404F68 of the file /cgi-bin/login.cgi. The attack is possible to be carried out remotely. Attackers can send POST requests with page=login —no login required .Performing a manipulation of the argument hostname results in XSS. sub_4012A0 function defines a variable hostname, retrieves its value from the request packet, uses the sprintf function to concatenate it into v34, and finally passes the result to sub_404F68 for processing.However，the sub_404F68 function creates a response packet and places the unfiltered value of the hostname into the packet. |
